Improving seed germination and oil contents by regulating the GDSL transcriptional level in Brassica napus.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
key messageSeed germination rate and oil content can be regulated at theGDSL transcriptional level by eitherAtGDSL1 orBnGDSL1 inB. napus. Gly-Asp-Ser-Leu (GDSL)-motif lipases represent an important subfamily of lipolytic enzymes, which play important roles in lipid metabolism, seed development, abiotic stress, and pathogen defense. In the present study, two closely related GDSL-motif lipases, Brassica napus GDSL1 and Arabidopsis thaliana GDSL1, were characterized as functioning in regulating germination rate and seed oil content in B. napus. AtGDSL1 and BnGDSL1 overexpression lines showed an increased seed germination rate and improved seedling establishment compared with wild type. Meanwhile, the constitutive overexpression of AtGDSL1 and BnGDSL1 promoted lipid catabolism and decreased the seed oil content. While RNAi-mediated suppression of BnGDSL1 (Bngdsl1) in B. napus improved the seed oil content and decreased seed germination rate. Moreover, the Bngdsl1 transgenic seeds showed changes in the fatty acid (FA) composition, featuring an increase in C18:1 and a decrease in C18:2 and C18:3. The transcriptional levels of six related core enzymes involved in FA mobilization were all elevated in the AtGDSL1 and BnGDSL1 overexpression lines, but strongly suppressed in the Bngdsl1 transgenic line. These results suggest that improving the seed germination and seed oil content in B. napus could be achieved by regulating the GDSL transcriptional level.
